I would go with a second hand gun for that price,, you will find you can get alot more for your money ,, smk guns are not the best but if its for plinking and cans etc then it should be ok ,,, if he likes the idea of a bolt i would try a crosman ratcatcher and they are light and great fun !! Or a break barrel like a bsa lightning , second hand of course
Sorry for the essay !! Haha
